About this map

Sourdough serves as a central point of reference in this Sweet Grass County landscape, situated at the intersection of Rapelje Rd and Sourdough Rd. The terrain is defined by a dense network of coulees and draws, including Nash Gulch, Tangen Draw, and Gunnerson Draw. These landforms funnel water toward a series of prominent drainages, most notably Sweet Grass Creek and its various tributaries such as Ryan Cr and Hamilton Cr.

Water management and natural irrigation are evident through features like the Glass Lindsay Lakes Lower Reservoir in the northern portion of the quadrangle. This area of Montana is characterized by its rural layout, divided by the Public Land Survey System into townships like t3n r15e and t2n r16e. The map provides a look at the contemporary road network and hydrological patterns, reflecting the agricultural and ranching foundations of the region.
